AARN C. VAUGHAN, OF PHILADELPHIA, PENNSYLVANIA, .ASSIGNOR TO HIMSELF ANDPt. W. PARK, OF SAME PLAGE.

IMPROVEANI ENT IN LAM P-BURNERS.

To all whom it may concern:

Be it known that I, AARON C. VAUGHAN,

' 0f Philadelphia, Pennsylvania, have invented an Improved Lamp-Burner;and I do hereby declare the following to be afull, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon.

My invention consists of a tubular wick,

through which the air can pass, a perforated casin g, and a ange, thewhole being arranged substantially as described hereinafter, so as toproduce from ordinary-coal-oil a most brilliant name.

My invention further consists in making the said iiange adjustable, soas to regulate the extent of or entirely extinguish the iiame; also, inmaking part of thewick-tube detachable, so that the adjustment of thewic'k may be readily effected.

In order to enable others skilled in the art to make and use myinvention, I will now proceed to describe its construction andoperation.

On reference to the accompanying drawings, which form a part of thisspecification, Figure 1 is a sectional elevation of my improvedlamp-burner; Fig. 2, a plan view of Fig. l, and Figs. 3, 4, and 5,illustrative diagrams.

A is an oil-reservoir, which is supported on a suitable stand, and whichcommunicates Vthrough a pipe, a, with a burner consisting of twocoi'icentric'tubes, B C, having an annular space, x, between them.

The tubes B C extend above the reservoir, and in the annular space x,which is closed at the lower end, fits a tubular wick, b.

A section, d, of the upper portion of the tube B is detachable; andbelow the tube C is a perforated casing, D, through which air can passinto the interior of the tube.

The upper end of the burner is surrounded by a perforated casing, E,which is consider- 1 ably larger in diameter than the tube B, and

is adjustable vertically thereon; and at the upper end of the casin g isan annular flange, o, the inner edge of which isV above the wicktube, orrather projects beyond the same, as seen in Fig. 3; or it may evenproject to the' extent seen in Fig. 4.

Ou the flange e are pins or projections f, which serve to retain in itsplace a glass chimney, X.

The reservoir A is filled with ordinary illuminating coaloil. rIhe wickZ) is thoroughly saturated and trimmed so that its upper edge shall beeven, or thereabout, with the upper edge of the burner. A light is thenapplied to the Wick, and the casing E is adjusted until the iiange e isa quarter of au inch, or thereabout, above the top of the burner.

The size of the liame may be varied by ad justing the casing E so as toraise or lower the iiange c, thereby increasing or diminishing thesupply of air to the flame, and the latter may be extinguished bylowering the casing until the flan ge rests ou the top of the burner.

I have found by repeated careful experiments that by the use of atubular wick, combined with the perforated casing and ange e, in themanner described, a most brilliant flame may be produced from ordinaryilluminating coal-oil.

It is not necessary that the entire perforated casingE should beadjustable; in fact the casing itself may be permanent7 and the iiange cso arranged as to be adjustable. (See Fig. 5.) Nor is it necessary thatthe wick and wicktubes should be cylindrical, as they may be made of anoval form without impairing th quality of the flame.

The object of the detachable section is to afford facilities for theadjustmentof the wick to and the Withdrawal of the same from its place,this manipulation of the wick being easily accomplished after thesection d has been detached.

I claim as my invention and desire to secure by Letters Patent- 1. Thecombination of the tubular wick with the perforated casin g E and iiangethe whole being arranged substantially as and for the purpose described.

2. The wick-tubes B and C, with their tubular wick, in combination withthe flange e, rendered adjustable to and from the top ofthe wick-tubes,substantially as described.

3. The detachable continuation dof the wicktube B, for the purposedescribed.

In testimony whereof I have signed my name to this specification in thepresence of two sub scribing witnesses.

AARON C. VAUGHAN.
